Mouth guards and mouth splints
If you grind your teeth while you're asleep, it may help to wear a mouth guard or mouth splint at night.
Mouth guards and splints even out the pressure across your jaw and create a physical barrier between your upper and lower teeth to protect them from further damage. They can also reduce any grinding noises you make at night.
Mouth guards are similar to those used in sports such as boxing or rugby. They're rubber or plastic and can be made by a dentist to fit your mouth. You can also buy a mouth guard from a pharmacist, but it's unlikely to fit as well as a custom-made one.
A mouth splint is made from harder plastic and fits precisely over your upper or lower teeth. They're no more effective than mouth guards in reducing the symptoms of teeth grinding. But they're more expensive as they last for several years, whereas mouth guards usually only last for less than a year.
You'll usually have to pay for a custom-made dental appliance. It's often a band 3 treatment, but may be more expensive, depending on the type recommended and how it's made. Ask the dentist about the available options and how much they cost.
Treating stress and anxiety
If the underlying cause of your teeth grinding is stress or anxiety, psychological treatments, such as cognitive behavioural therapy (CBT), may help.
If your teeth grinding is stress-related, it's important to try to relax and get a good night's sleep. There are a number of things you can try to help you wind down before you go to bed, including:
- deep breathing
- having a bath
- listening to music

Breaking the habit
Habit-reversal techniques are designed to break your teeth grinding habit. But there's no scientific evidence to suggest that using habit-reversal techniques will cure teeth grinding.
If you're awake when you grind your teeth you might find it useful to record how often you grind your teeth each day. You can then work out when you're more likely to do it and why – for example, when you're concentrating or stressed.
If you're aware of your habit it will be easier to break. To break the habit, you could train yourself to relax your jaw when you feel yourself grinding or clenching. For example, you could open your jaw slightly or gently place your tongue between your upper and lower teeth.
Habit-reversal techniques may be used by a specially trained therapist, or you can try them yourself using a computer program or self-help book. A GP will be able to advise you.
Treating and preventing dental problems
You should have regular dental check-ups so that any problems caused by your teeth grinding can be treated as soon as possible to prevent further damage.
Dental problems, such as misaligned, cracked, crooked or missing teeth, can usually be treated with reconstructive dental treatments, such as false teeth, overlays and crowns.
These treatments can sometimes reshape the chewing surface of your teeth and stop you grinding. You'll usually have to pay for this type of dental treatment and it's often expensive.

Your GP may suggest taking a muscle relaxant before you go to bed to help relieve your symptoms.
If your teeth grinding is a side effect of taking antidepressants, your GP may suggest changing your medicine. Never stop taking medicine that's been prescribed for you without consulting your GP first.
